Patent JP-H11137976-A (JP)
Title: Filter device
Inventor: NOGAMI HIROSHI
IPC: B01D63/02
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To regenerate a filter to recycle by supplying an original liquid to one of two filter units, taking out a permeated water to the outside and providing a permeating side communicated flow passage communicating the filtering sides of two filter units with each other and a back washing water take-out flow passage provided at the original water flow-in side. SOLUTION: When a three-way valve 4 is switched to communicate a feed pipe 2 and a water supply pipe 112 with each other, a feed supplied from a water supply flows in a hollow yarn filter 111 to permeate a hollow yarn membrane and flows out as a permeated water from a permeated water flow-out pipe 115 to a permeating side communicating pipe 5. A control device 7 detecting that the pressure difference between the front side and the back side of a hollow yarn filter 111 exceeds a fixed value outputs the order to switch the three-way valve 4 and to open a stop valve 611. As a result, the feed flows in the hollow yarn filter 121 to be filtered. A part of the permeated water flowing out to the permeating side communicating pipe 5 flows in a hollow yarn filter 111 to wash out soil on the hollow yarn membrane and is taken out from the back washing water take-out pipe 61.

Title: Vortex flowmeter
Inventor: YOSHIKURA HIROSHI
IPC: G01F1/32
Filed: 1989-11-24
Abstract: PURPOSE:To reduce phase modulation and to increase the range of measurement by shortening a propagation distance at which phase modulation is imposed on an ultrasonic wave by Karman vortexes. CONSTITUTION:When fluid flows in a conduit 6, a vortex generation body 7 generates Karman vortexes. An ultrasonic wave transmitter 9a and a receiver 9b are fitted to fitting holes 6a and 6b so that the line connecting the fitting holes 6a and 6b slants at a specific angle theta to the horizontal line perpendicular to the extension direction of the vortex generation body 7 and phases the axis. The ultrasonic wave propagated in the fluid is modulated with the sped by the Karman vortexes, so the phase of the received ultrasonic wave varies in a half-cycle sine wave shape as the Karman vortexes pass. This phenomenon is utilized to count the number of the Karman vortexes. The passing direction of the ultrasonic wave slants by theta, so the phase modulation becomes small and the range of measurement is increased.

Title: Method and device for counting film for camera
Inventor: NISHITANI YASUHIRO
IPC: G03B17/36
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To realize counter display preventing the taking-out time of a film cartridge from being mistaken. SOLUTION: By this method, the number of photographed frames is displayed on a display means when the rewinding action of a film is started and a display number obtained by subtracting one by one from the number of photographed frames during the rewinding action of the film is successively displayed on the display means. The subtraction on the display number displayed on the display means is operated late in comparison with a case that the subtraction is operated one by one by detecting the winding-up of one frame when the film is rewound. Thus, the time that the film cartridge can be taken out from a camera and the time that the display number becomes zero or 'E' resulting from that the display number displayed on the display means is successively subtracted can be made to match each other.

IPC: G03C3/00
Filed: 1990-11-13
Abstract: PURPOSE:To effectively transmit the rotational power of a spool at the time of rotation thereof also to the end part of a film by forming a rear end regulating part for regulating the receding of the film rear end, on the spool. CONSTITUTION:A rear end regulating part 22 for regulating the receding of a film rear end part 15a, by being abutted on the end of the film rear end part, at the time of the rotation of a spool 14 in the direction of feeding a film 15, is formed on the spool 14. When the spool 14 is rotated so as to feed the film 15, the film rear end part 15a is pushed back in the receding direction due to the load added to the film at the time of feeding, however, since the movement of the film rear end part 15a is regulated by the rear end regulating part 22 provided on the spool 14, the end by which the width of the rear end part 15a is narrowed, is not strongly pressed to the axis part of the spool 14, and a crack is not generated on that part. Even when some load is added, film feeding can be stably carried out.

Abstract: PURPOSE:To easily obtain a color filter by forming a dyeable film by formation, predrying and hardening treatment of the dyeable film, then iterating only the operations for printing and drying by as much as the number of colors, then subjecting the film to a fixing treatment. CONSTITUTION:The film which is dyeable with an anionic dye formed by imparting a dyeable group and photosensitive group or thermosetting group to casein, etc., is formed on a transparent glass plate. The anionic dye is an acid dye, etc., which are heretofore known and a glue is known synthetic glue, etc. The color tone of the dye is adjusted by adjusting viscosity and adding a dye thereto. The prescribed pattern is printed by the color dye of a 1st color having a prescribed spectral characteristic on the dyeable film and is dried. The stripe or mosaic patterns are similarly formed successively by the plural dye glues. The film is thereafter subjected to, for example, the fixing treatment. One layer of the dyeable film is selectively dyed by printing according to this constitution; therefore, the dyed film is extremely thin and the color filter having good transparency is obtd.

Abstract: PROBLEM TO BE SOLVED: To access multi heads and print at all times by providing a printing means with a distributing transferring means for distributing and transferring image data in an ink-jet printer having the printing means including at least a plurality of multicolor heads. SOLUTION: Image data input from an image data input part 30 is brought in an image process part 40, where the data is subjected to a predetermined image-processing. The image process part 40 divides the image data of one sheet after the image-processing to three and transfers the data to corresponding responsible printer units 50. Each printer unit 50 drives a multicolor head 51 based on the input image data, so that one sheet of the image is printed as a whole. In other words, one sheet of the image is divided to three A-C areas and the A-C areas are serially printed by first - third multicolor heads 51. When the multicolor heads 51 finish printing the areas of respective responsibilities, one sheet of the image is completed fully.

Title: Lost form method for stainless steel casting
Inventor: BURAIAN HANDO
IPC: B22C9/04
Filed: 1993-11-15
Abstract: PURPOSE: To obtain a process capable of manufacturing low carbon stainless steel parts by a lost foam casting process. CONSTITUTION: A sand packed chamber 10 containing a plastic pattern 18 of the parts is formed. This sand packed chamber is capped with a front surface film 26. A vacuum within a range of a mercury column of 20 to 29 inches (50.8 to 73.7 cm) is applied through an opening 30 into the sand packed chamber. Molten stainless steel is poured through sprue and runner systems 20 and 22 into the plastic pattern region and is replaced with the plastic pattern 18, by which the low carbon stainless steel parts are formed. The high vacuum applied to the sand packed chamber 10 in which the stainless steel is poured not only accelerates the pouring of the molten metal by the suction of the molten metal into the assembly pattern but is capable of discharging the carbon haze from the chamber 10 during the pouring process.
